Modern CPUs are incredibly fast but often idle while waiting for data. To keep busy, they "speculatively" execute future instructions based on predictions, essentially guessing what the next task might be. While this guessing is wrong, the results are normally discarded and unnoticed by running programs. However, Spectre uses a side-channel attack to trick a program's speculative execution into leaking sensitive data from privileged memory areas, such as passwords, encryption keys, or personal files.
